During the boss battle against the MG Rays on Arsenal Gear, you can shoot them in the leg with a stinger missile, making them cry out in pain. Quickly shoot another stinger missile at its head and this will take more damage off it's life gauge.

During the Plant mission when you have to fight the Metal Gear RAYS, start off by shooting a few Stinger missiles into the middle RAYs legs mouth etc. then ditto to the other RAYS on either side. Then when the middle Ray jumps onto the platform run to the right or left of it and keep firing away those missiles. Do the same with the others as they appear. Don't stay in the middle of the arena as you leave yourself open for many deadly attacks & 'mission faileds'. At the side of the arena they have less distance to attack you and therefore can only use certain attacks.

When you fight Fatman in the Big Shell chapter if you have some trouble finding the location of the bombs he plants, quickly change to the thermal goggles in the area and it should make the bomb easier to find and you might save some valuable time this way.

As soon as you have to fight Vamp in the B1 Filtration chamber #1, Vamp will do his infamous pose then starts swimming around in the water, when he does this quickly run north and wait. When Vamp resurfaces, jump over the railing and hang there. Vamp will simply walk up to you and try to slash your hands. at that exact time, quickly jump up and do the 3 x combo kick to throw him back into the water. this will drain his stun gauge. Keep repeating the hanging and combo kick process untill he is defeated. Note. This trick works best if your grip gauge is at level 2.

Get the lvl 2 security card and head to Strut F the warehouse.Go to the lower floor take out the guard and go through the level 2 door.The AKS-74U and suppressor will be in there.Then go up the stairs and take out the other guard.(If you wanna have all dogtags just hold up the two guards)Go to the left and open the door.Don't walk in because there's a C4 trap.look to the upper left wall and shoot the green light.Walk to the back of the room and there are two boxes one with the M4 and one with M4 bullets.

Fist-fight him. On easy, one good melee will knock about half of his stamina off. The best time to catch him is when he jumps out of the water, lands and stands up and spins. If you're close enough when he does this, run up and punch him out. You can also sometimes get him when he's recovering from a hit, like stepping on a mine or some C4.

After you rescue Emma and arrive back at the Shell 2 core, 1F Air Purification Room. Leave her in a safe place then kill/stun the guard in the room on the left where the node is. Then grab Emma and take her into the small room where the two gun mounted surveillance cameras are(make sure you disabled them first)and leave her there. Go out turn left and stun/kill the next two guards down the stairs. Now go out of the 1F Air Purification room to the KL connecting bridge then come straight back inside and go to the room where you found the President, Emma will now be in that room so you don't have to worry about any extra Guards bothering you and you can get her out safely.

When Solidus attempts to suffocate you with his "arm extensions" on top of the arsenal gear you are supposed to press a certain button repeatedly in order to survive (triangle button in my game). While in difficulties from easy-hard this isn't impossible, many people isn't able to pass this test on extreme and european extreme, and not everyone who can't pass the "test" can go and buy a an auto-fire controller.So there is a trick that makes your O2 gauge drop slower (this doesn't mean that you have to stop mashing the button when he suffocates you). Now when the cut-scene on top of the Arsenal Gear begins, you can't move, but you can "turn your head" so move to the left; you'll see Snake and Fortune there. When Solidus stops talking and starts to suffocate you quickly start pressing the button but at the same time turn your head to the left again, but now you can turn "more" to the left, up to a point where you will be able to see Ocelot, keep the analog stick to the left to keep watching Ocelot while you mash the button. Believe it or not now your O2 gauge will drop slower, I know it doesn't make any sense why this happens, but it is true. It was thanks to this I was able to survive in both extreme and european extreme.

Hostages Responses:On the part where you have to look for Ames, with the directional microphone, there are some hostages that will have some funny responses if you press the action button, while the d. mic is equipped and pointed, at them. An old lady near the flagpole will shake and tremble, and actually pee, if you do the above action. Another lady hostage, a young woman, will actually talk to you. She will say "My name is Jennifer," the first time you do it. On the second time, Jennifer will reply, "Stay away from me!" You better be careful on doing this with Jennifer because it might get you in trouble.

MGS1 Soldier:When you have found Ames, there will be a codec transmission happening. After the transmission, you will have to use your d. mic again to listen in on a conversation by Ocelot and Solidus Snake. When the conversation starts, quickly turn the d. mic where the flagpole is. If done in the correct direction, you will hear the familiar soldier from Metal Gear Solid (the one that was always constipated) talking to himself about Olga and Sniper Wolf.

Emma's talk about Raiden:When Emma has to walk on the Strut L oil rails, you will have to use the PSG1 to "escort" her. You have to ask Snake to snipe for you, in order to do this. Use the d. mic and point it towards Emma. She will repeatedly say things such as "I can't do this" for a few times, but when she gets into one of the columns, she will begin talking about Raiden's appearance.

MGS1 Soldier's Appearance #2:In order to do this trick, you have to do the above trick, first. When Emma reaches the second column, the same soldier from earlier will scream at her "Freeze!". You can listen to the rest of the conversation yourself.

When Emma is crossing the oil fence coming towards the last part of it, point the DMic up to Snake in his sniping position and he will say things like "Hm not bad at all", and "i wonder if i need to clear things with Otacon before asking her out" <img src="http://staticneo.com/neoassets/smileys/a_tongue.gif" border=0 vspace=2 alt="" />

If you've played Snake Tales through. U'll find that in the totally weeeird 'External Gazer' mission at sum point on the text screen, Mei Ling will announce that she is married 2 er Solidus? Hey, wtf...? :B

In Shell Core 1, B2 you will find girly books on top of some lockers. Punch the locker where they are a few times in order for the books to come down, then grab them. Then every 'continue' or 'saved game' when you find yourself back in B2, there will always be more books on top of the locker for you to use throughout the rest of the game.

Metal Gear Solid 2: Substance Easter eggs

In the Plant mission, when you are in the B1 Filtration Chamber No. 2 and you have to rescue Emma, swim up to the air pocket that looks into the locker room where Emma is and you will see her in there. Look at her long enough and you will get a call on the codec from Rose who jealously questions Raiden for perving too long..

When you are in the Shell 1 core, 2F, provided you hav the stealth camo. equip it then go to the bird in the cage and shoot at it 3 times. It will then say 'enemy sighted. requesting back up!' or 'he's here. someone get over here'. Look at your soliton radar at that moment you will see all of the guards field of vision suddenly turn red. This is better when reinforcment guards are wandering around the area also. it's like your radar will go...well RED!

If you have the stealth camo. equip it then hold up a guard. Go around to face him in FPV then quickly un-equip the stealth camo and your gun. you will then see a flash of two stars in their eyes which will trigger alert mode. It's up to your own devices what you do next..

Metal Gear Solid 2: Substance Cheats

It is helpful when in the boss battle with Fatman to lay down a few claymore mines in various spots. That way, while you are running around difusing his bombs, and he is skating around taunting you and planting more bombs, the mines can do some of the job of killling him. That is to say, instead of relying solely on cathcing up to him and shooting him, you can also get part of the job of killing him done this way while you are busy defusing bombs, and time spent difusing bombs is not time spent 100% without inflicting any damage on him. Now, he won't run into every mine you lay, he may only run into one or two, but it helped me kille him. It also helped me conserve gun amo because I did not have to always rely on shooting him to get him to fall in order to get a shot or two blasted in his big bald head. The bombs would lay him out in one felled swoop and all I had to do was run over and shoot his head before he got up. Now, you have to be sure not to run into the field of view of the mines yourself but I did not have trouble avoiding them. Hope this helps you. Also, when fighting Vamp, you can shoot him with stinger missles even when he is under water. Also, if you launch a grenades into the water, they will inflict damage on him when he swims into them. I submitted these tips because I did not see them anywhere else.

get close to the metal gear so it will only be able to shoot a laser at you.this can easily be dodged it also leaves its mouth vulnerable to attacks which when shot at will cause more damage.dont get too close though or it will attempt to knock you off your feet which makes you vulnerable to its attacks. also don't get far away either as it has a wider range of attacks which are not as easily dodged.

You can use the boxes to help you move around the big shell. This works only in the parcel room. Climb onto the parcel table next to the conveyor belt. If you equip yourself with a cardboard box the conveyor belt will stop alowing you to climb on.

Cardboard Box 1 takes you to "Strut C Dining Hall".

Cardboard Box 2 takes you to "Transformer Room on Strut B".

Cardboard Box 3 takes you to "strut A Pump Room."

Cardboard Box 4 takes you to the "Warehouse Strut F".

"Cardboard Box 5 takes you to a Dispatch Point from Strut E to the Locked Room

Instead of messing about sneaking around the shell 1 core to get th AK, go to strut f (warehouse) and as you go down the stairs, to your left (raiden's right) there is a door with a level 2 mark on it. Go through there and search around for it. The AK suppressor is also in here so look hard.

Start by putting in the documents of metal gear and do as many of the missions as possible.Save then put in the other disk in load a new game on the vr missions and put your name as ? leave everything else except nationality which you put a ? in as well.You will now have all the characters with 00%
